But six times in the Sermon on the Mount, he introduced what sounded like statements from the Hebrew Scriptures with the words: “It was said.” (Matthew 5:21, 27, 31, 33, 38, 43) Why? Because he was referring to the Scriptures as interpreted in the light of Pharisaic traditions that contradicted God’s commandments. (Deuteronomy 4:2; Matthew 15:3)

17. What better way than “eye for eye and tooth for tooth” did Jesus teach?

17 Jesus next said: “You heard that it was said, ‘Eye for eye and tooth for tooth.’ However, I say to you: Do not resist him that is wicked; but whoever slaps you on your right cheek, turn the other also to him.” (Matthew 5:38-42) Jesus is not here referring to a blow intended to do injury but to an insulting slap with the back of the hand. Do not degrade yourself by swapping insults. Refuse to return evil for evil. Rather, return good and thereby “keep conquering the evil with the good.”​—Romans 12:17-21.
